This invention relates to an antenna device. It has for its objecttheprovision of an antenna of the verticalgtypevwhich can be normally woundy upy'out of they way and yet quickly released and elevatedor use by means of an inflatable buoyant carrier such as a balloon.` j j r A further object comprises the provision of a means whereby the carrier element can be always ready to elevate the antenna and yet when not in use can be stored away.

The invention is illust-rated in the drawings, of which Figure 1 is a perspective view of the device showing the antenna in its elevated position.

Figure 2 is a partial perspective view showing the antenna and the carrier element stored away.

The form of the invention shown in the drawings is a preferred form, although it is understood that modiiications in the construction and arrangement of the parts and in the character ofthe materials used may be adopted without departing from the spirit of the invention as set forth in the appended claims.

In its general aspect the invention comprises a conductor element to act as an antenna which is preferably wound on a reel,

the free end thereof being connected to a Y carrier element of the buoyant type, such as a balloon. This carrier element is normally enclosed in a receptacle out of the way,

and the antenna wire is normally wound up f on the reel. The carrier element is normally disposed in a box -having collapsible sides, held together in their closed relation to house the carrier element, by means of a cover. The neck ofthe balloonis normally in connection with a reservoir containing buoyant fluid, so that after the box `has col' lapsed to release the balloon, it can be quickly inflated.

In the preferred kform of the invention shown in the drawings I show a base 10 y in which is mounted a reservoir 11, a box 12, having a cover 13, a reel 14 having an operating handle 15 anda suitable brake mechanism 16.

0n this reel is wound an antenna wire 17, the free end of which is connected by cords 18 to an iniiatable carrier element or a balloon 9. This balloon has a neck 2O which is preferably provided with an automatic valve of the automobile type, although the construction of this valve is not shown. The

sidesof the box 12 are preferably so hinged or pivoted tok the baseqlO that 'they will collapse and `fall apart as *soon` as the cover 13 is removed. The side of the box adjacent the reservoirll is provided with.k a notch 21 through` which the neck .20, offthe balleon extends." @This neck is "normally connected to a pipei22 lleading from the reservoir, this pipe containing a valve 23.

Whenever it is desired to use the antenna, the cover is taken oil the box, permitting the sides to collapse, after which the valve 23 is opened,permitting the buoyant fluid to flow into the carrier element to inflate it. Thevalve 23 is then closed and the balloon or carrier element can be released to carry the antenna away upward, the brake 16 being used to control the elevation of the wire. When the antenna element has been elevated sufficiently the brake is applied and any suitable conducting wire, such las 24, is clipped on to the antenna wire as shown and is led to a suitable radio set.

In this way an antenna of any desired length is always readily available for use, an when vnot in use can be stored away in a simple, compact mannen The carrier element is always ready to be inflated and can be very easily and quickly released.

What I claim is:

titi` LApparatus for the purpose described, y

within the carrier element while being in- *y iiatedcausing the Vparts to be separated to release the carrier element.

'2. Apparatus- :torthe purpose described,"

including an inflatable carrier` element, an antenna wlre connected to sald carrier ele- .Inent, a container for the carrier element, lnflatmg means for inating said carrier element, said container consisting of relatively movable parts capable of being associated in container forming relationship, one of said parts having an opening therein, said carrier element having a portion adapted to extend through said opening and to which said inilating means is connected for the inflating operation, and the parts of said container being separated under the action of pressure within the carrier element while the carrier element is being inated to release the carrier element.

3. Apparatus 'for the purpose described including an inflatable carrier element in the form of a bolster, an antenna wire connected at one end to said carrier element, a container for the carrier element, said container comprising hin ed sides and a anged cover adapted to hol said sides in container `forming relationship said covei` bein removable to allow said sides to :move on 't' eir hinges respectively to oe disposed in the same horizontal plane.

4. A paratus for the purpose described including 'an inatable carrier element in ltainer comprising the form of a bolster, nn antenna wire connected at one end to said carrier element, a container for the carrier element, said conhnged sides and a flanged cover adapted to hold said sides in container forming relationship, said cover being removable to allow sald sides to move on their hinges respectively to be disposed in the same horizontal plane, one of said sides havin an vopening therein, inflnting means, said carrier element havin a portion adapted to extend throu h sai opening and be connected to said in ating means for the inflation of the carrier element.
